Scared straight

Today Tyler was throwing a fit (can 4 mo. old's throw fits?), well whatever it was he was screaming so hard that he started to gag and then stopped breathing. His face turned grey and I totally panicked. I started to shake him (gently) to make him breathe again and he started to get a little color in his face and then took a big gasp of air. I don't think I have ever been so scared in my life. Man I love that little boy!
